Is there still a 3-level centimeter? It's not necessary, and it's not pretty.
Look at the living room area, if the area is not particularly large, 50cm wide is obviously over, I have handled a lot of customers, the general living room, a ceiling can not reach this width. If a designer wants to make such a design, you can ask him what he thinks and what he intends, after all, this is not a one-size-fits-all approach.
If the top surface of the secondary ceiling is 45 cm, it should be this width.
In mutual. Multiply and divide to know the area. Or let a professional handle it for you.
The width should not be less than 50 cm.
Otherwise, the width is too small, the thickness is large, and it looks bulky. >>>More
15 height is sufficient, of course, it can also be adjusted appropriately, mainly for aesthetics, or according to the elevation to judge.
